What's New in VidNeatDown 3.4.6:

• YouTube Video & Audio Downloads: Seamlessly resolve adaptive streams, download high-definition video formats, and extract audio tracks directly in Firefox (subject to Terms of Service).
• Adaptive Multi-Connection Ramp: Intelligent connection slow-start ramps downloads smoothly and avoids network saturation, with automatic throughput stabilization across DASH and multi-lane downloads.
• Universal Speed Engine: Replaced spike-prone instant measurements with a smoothed 3-second EWMA throughput sampler. Real-time download speeds and stalled-stream indicators are now significantly more accurate.
• Offscreen Pause & Resume Guard: Extended safety watchdogs to offscreen downloads, preventing wedged pause buttons if worker acknowledgements drop and ensuring accurate restart states.
• YouTube Video + Audio Remuxing: High-definition adaptive video and audio tracks are paired and remuxed on-the-fly locally into playable MP4 files with zero quality loss.
• UI & Queue Polish: Added single-card dismissal for completed downloads, improved rescan reliability, and optimized tab switching behavior during active downloads.
